Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741408, here are decompositions:

7 + 8741401 = 8741408
37 + 8741371 = 8741408
61 + 8741347 = 8741408
79 + 8741329 = 8741408
139 + 8741269 = 8741408
157 + 8741251 = 8741408
271 + 8741137 = 8741408
337 + 8741071 = 8741408

Showing the first eight; more decompositions exist.
